IMPROVEMENT IN FUNNELS.

a y The Schedule referred to in these Letters Patent and making part fthe sante.

lejo, in the county of Solano, and State of Calitbrnia, have nl ventedcertain. new and useful Improvements -in Funnels for Liquids and Fluids;and I do hereby -declare that the following is a full and exactdescription ottlle'same, reference beinghad tothe accompany-v ing'drawings, and to the letters of reference marked thereon. l

lThis invention relates to funnels; and consists,

mainly, in the employment of a ball-valve, which is located atthe lower'opening of the funnel, and attached toia jointed rod. v

By the' movement of 'the rod, through the medium of suitable devices,which will be fully described hereinafter, the valve-is opened'- andclosed'atpleasure. lhe form of the valve is such as to permit the liquidto pass over it when opi-n, without aiording'it any. oppmtunityforlodgement, and the jointcdrod permits it to be swung aside readily whendesired.

By this construction and arrangement, the contents of the Yfunnel willbe much more rapidly discharged than when the ordinary fiat valve isused.

The outer plate is perforated near the base, through which the airescapes into the chamber.

A vertical pipe or well extends from the top to a point just below wherethe nozzle is joined to the main portion of the body. In this welloperates a plungerrod, and to the lower end of which is attached a'ball-v va' ve.

lo the upper end of the plunger is attached, by a hook land eye, a smalllever, which has its fulcrum on a plate connected to the rim, and whichis operated by a small spring.

A strainer is placed above the nozzle, a'nd an-airtube extends down theinterior of the funnel, in the same manner as that described in 'myformer specification, which connects with the air-chamber above de#scribed.

lhe outside of ythe nozzle is provided with a cover or jacket,oflndia'rubber, also described in my former application.

Referring to the drawings-A Figure -1 is an elevation, showing theball-valvoleered.

` and seal.

Figure 2 is a vertical section, showing thc ballvalvc closcdor drawnupin the end of the nozzle.

The nozzle of my funnel I construct with' double walls, so as to form anair-chamber, a, which has` no connection witlrthe interior of -thefunnel.

The outer plate or jacket b is pierced near the` base with holes c c c,so that the air, when the bottle is being filled, will escape into thechamber and pass oli` through the-air-tube'lzl, and thus relieve thebottle of atmospheric pressure. Y L

The India-rubber jacket c should not extend to the end of' the nozzle,so as to cover the air-holes, asin that case the air would pass uparound the ball-valve, and have a tendency to check the dow through thenozzle. r

The valve f may be spherical or oval, so that when fit is drawn up intothe end of the nozzle it will be water-tight; and I 'am confident, afterrepeated experiments, that no other shape will-answer, as, forinstance,where a button-valve is used, the fluid,v when ruiming down, will strikethe tlat surface, and spread outagainstlt-lie neck f thebottle, andpartiallysum the How, the only mediinn for the cscapelot' the air beingthe vert-ical pipe g.

My'valve is linked bya rod or pli1i ige1', h, which passes upth'rouglrthe vertical pipe above described, and ishooled to athumb-lever, i, which has its fnlcrum on the half plate k.

Back of the fnlerum is a spring, b, and when the pressure of the thumbis removed from the end el' the'j lever, the spring carries the plungerdown the pipe, I

and the ball-.valve drops, to admit of the escape ofthetluid intotliebottle.

A gaugeA for` measuring the quantity to be drawn may' be'placed in thefunnel, butthis device lf` do not" lay-any specialclaim to.

Having thus described my invention, What I claim, and desire to securebyLetters Patent, is-,-

A luncl, in which are combined and arranged the jointed rod lL, operatedas described, the guide-pipe g, the ball-valve f, thetube d, and thejacket c, all as and for the purpose described.

In witness whereof, Il1ave' hereunto set my hand Witnesses:
